Filed Aug. 5, 1963, Ser. No.299,774 2 Claims. (Cl. 15-248) This invention relates generally topainting tools and equipment, and more particularly, it relates to anedger attachment for paint brushes.

The edger attachment of the present invention generally includes ashielding plate pivotally mounted on a paint brush for movements betweenan operative position for guiding the bristle end portions of the brushand an inoperative position away from the bristles of the brush.

An important object of the present invention is the provision of anedger attachment for paint brushes which is particularly useful intrimming or edging along the margin of a surface to be painted so as toprevent the overlapping of the paint upon the adjacent surfaces.

Another object of the present invention is the provision of an edgerattachment for paint brushes which is particularly useful in paintingthe inside corners of walls and ceilings and which is also extremelyusefull for painting casings and window sash where it is desirable toprevent the overlapping of paint onto the adjacent surfaces.

A further object of the present invention is the provision of an edgerattachment for paint brushes which is provided with adjustable mountingmeans so as to permit the attachment of the shielding plate in thedesired position.

Another object of the present invention is the provision of an edgerattachment for paint brushes in which the shielding plate thereof isdisposed and arranged so that the guiding edge portion is spaced abovethe bristle end portions of the normally straight bristles whereby theedge portion of the shielding plate generally coincides with the bristleend portions when the bristles of the brush are flexed for painting.

A still further object of the present invention resides in the provisionof an edger attachment for paint brushes in which the shielding platemay be quickly and easily moved to an inoperative position to permitdipping of the brush in a paint container, and in which the shieldingplate of the attachment is mounted for quick and easy removal forcleaning purposes.

Other objects of the present invention reside in the provision of anedger attachment for paint brushes which permits extremely accuratepainting along edges of marginal surfaces, which is easy to use withoutthe possession or attainment of extraordinary skill, and which lendsitself to economical manufacture.

The above and still further objects and advantages of the presentinvention will become apparent from a consideration of the followingdetailed specification, attached drawings and appended claims.

Referring to the drawings, wherein like reference characters indicatelike parts or elements throughout the several views:

FIG. l is a View in perspective showing the novel paint brush edgerattachment of the present invention in its operative position;

FIG. 2 is a View in perspective showing the edger attachment in itsinoperative position for dipping of the brush into a paint container;

FIG. 3 is an enlarged plan View, showing by broken lines the alternativebrushing or flexed position of the bristles of the brush;

FIG. 4 is a view in section taken on the line 4w-4 of FIG. 3, andshowing the brush and attachment in an operative painting position; and

FIG. 5 is an enlarged view in section taken on the line 5-5 of FIG. 3.

. Referring more particularly to the drawings, the reference numeral 1represents av paint brush in its entirety to which my novel edgerattachment is secured. The paint brush 1 includes a handle 2 extendingfrom the head 3 of the paint brush 1. The reference numeral 4 representsthe bristles of the paint brush which are secured in the usual manner bya binder 5 to the paint brush head 3 by means of an annular band 6.

The novel edger attachment provided in accordance with the presentinvention includes a mounting bracket, represented generally by thereference numeral 7, comprising a back plate portion 8 having a pair oflaterally spaced slots or apertures 9 therein. The mounting bracket 7 issecured to the head 3 of the paint brush 1 adjacent one side thereof bymeans of a pair of screws 10 or the like which project through theapertures 9, as shown particularly in FIGS. 3 and 4. The mountingbracket 7 further comprises a pair of axially spaced and aligned endjournals 11 for pivotal mounting purposes, as will be particularlydescribed hereinafter.

The edger attachment further comprises a generally at shielding plate 12formed from generally rigid sheet material, such as sheet metal orplastic. The heel portion 13 of the shielding plate 12 is formed todefine a generally tubular journal 14 adapted to t between the spacedjournals 11 of the mounting bracket 7, as shown particularly in FIG. 3of the drawings. The shielding plate 12 is removably mounted by means ofan elongated connecting pin 15 which extends through the alignedjournals 11, 14. The shielding plate 12 is thereby mounted for pivotalswinging movements between an operative shielding or guiding positionshown particularly in FIGS. l and 4 wherein the shielding plate 12 isdisposed adjacent the bristles of the brush and an inoperative positionaway from the brush, shown particularly in FIG. 2. It is noted that theconnecting pin 15 is frictionally engaged within the journals 11, 14 sothat the same may be removed to permit removal of the shielding plate 12from the brush 1 for cleaning purposes or for normal painting use of thebrush 1. Accordingly, the connecting pin 15 defines at one end thereof ahandle portion 16.

As shown particularly in FIGS. 3 and 4, the shielding plate 12 of theedger attachment defines the lower edge portion 17 which is flat andgenerally straight and which is adapted to guide and lineate the bristleend portions 18 of the brush 1, in the manner shown particularly inFIGS. 1 and 4 of the drawings. It is noted that the shielding plate 12is of a length designed to dispose the lower edge portion 17 thereof inspaced relation above the bristle end portions 18 of the brush 1 whenthe bristles 4 are in their normally straight condition. However, withthis arrangement, when the bristles 4 of the brush 1 are flexed orplaced in their condition for painting, as shown by the broken lines inFIG. 3, the lower edge portion 17 of the shielding plate 12 willcoincide generally with the bristle end portions 18.

In accordance with the present invention, the lower edge portion 17 ofthe shielding plate 12 is formed to extend in general parallelism withthe plane of the brush 1 when the shielding plate 12 is in its operativecondition, as shown in FIG. 4, whereby to guide and lineate the bristleend portions 18 of the brush 1 and prevent the overlapping of paint ontothe adjacent surfaces which are not to be painted. Another feature ofthe present invention is illustrated particularly in FIGS. l and 3,wherein it will be noted that the shielding plate 12, and particularlythe generally flat lower edge portion 17 thereof is wider than the widthof the brush 1 to which the edger attachment is adapted for securementso that when the bristles 4 of the brush 1 are flexed, as shown in FIGS.l and 3, the bristle end portions 18 will still be guided and directedby the shielding plate 12. With this arrangement, it is assured that thebristles 4 of the brush 1 will be guided at all times during paintingstrokes so as to prevent the overlapping of paint onto the adjacentsurfaces.

It will be noted that the heel portion 13 of the shielding plate 12 isnarrower than the main body portion thereof .and the shielding platetherefore denes outwardly diverging angle edge portions 19 which connectwith the generally parallel lateral edge portions 20 of the shieldingplate 12.

As shown particularly in FIG. 4, the shielding plate 12 is formed todene a tab 21 which extends generally laterally outwardly from thejournal 14 thereof for manual engagement by the users thumb, as shownparticularly in FIG. 2, for moving the shielding plate 12 to itsinoperative position, shown in FIG. 2. Also, the tab 21 may beconveniently engaged by the users thumb when the paint brush 1 and edgerattachment are -being used in the operative position, as shown in FIG.l, for holding the shielding plate 12 against the bristles for the brush1.

This invention has been thoroughly tested and found to be completelysatisfactory for the accomplishment of the above objects; and while Ihave shown and described above a preferred embodiment thereof in whichthe principles of the present invention have been incorporated, I wishit to be specifically understood that the same may be modified withoutdeparture from the scope and spirit of 4the appended claims.
